Ethereum utilities for restless

Package Exports

  • @restless/ethereum

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@restless/ethereum) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Restless - Ethereum

Ethereum module for restless. Uses ethers.js. Provides utilities such as:

  1. asEthAddress
  2. asBigNumber

Installation

npm install @restless/ethereum
yarn add @restless/ethereum

Sanitizers

asEthAddress

Accepts any string that represents a valid ethereum address. Checks the checksum if present. Returns a normalized representation.

asEthAddress('0xA5fE...f213', 'path') // Result.ok(0xA5fE...f213)
asEthAddress('0xa5fe...f213', 'path') // Result.ok(0xA5fE...f213)
asEthAddress('bla bla bla', 'path') // Result.error([{expected: 'ethereum address', path: 'path'}])
asEthAddress(123, 'path') // Result.error([{expected: 'ethereum address', path: 'path'}])

asBigNumber

Accepts any string or number that represents an integer. Converts the integer to a BigNumber.

asBigNumber('123', 'path') // Result.ok(BigNumber(123))
asBigNumber(456, 'path') // Result.ok(BigNumber(456))
asBigNumber(1.5, 'path') // Result.error([{expected: 'big number', path: 'path'}])
asBigNumber(true, 'path') // Result.error([{expected: 'big number', path: 'path'}])

asHexBytes

Accepts any string that encodes binary data of specific length in hex format. The returned string is always lowercased.

const sanitizer = asHexBytes(3)

sanitizer('0x12ab56', 'path') // Result.ok('0x12ab56')
sanitizer('0x12AB56', 'path') // Result.ok('0x12ab56')
sanitizer('0x12AB5', 'path') // Result.error([{expected: 'hex string representing 3 bytes', path: 'path'}])
sanitizer(1234, 'path') // Result.error([{expected: 'hex string representing 3 bytes', path: 'path'}])

asTransactionHash

Accepts any string that can be a transaction hash.

const exampleHash = '0xd04b98f48e8f8bcc15c6ae5ac050801cd6dcfd428fb5f9e65c4e16e7807340fa'

asTransactionHash(exampleHash, 'path') // Result.ok('0xd04b...40fa')
asTransactionHash(exampleHash.toUpperCase(), 'path') // Result.ok('0xd04b...40fa')
sanitizer('0x12AB5', 'path') // Result.error([{expected: 'transaction hash', path: 'path'}])
sanitizer(1234, 'path') // Result.error([{expected: 'transaction hash', path: 'path'}])
